Hey Cheri - the Indigo2 holds 2,000 and will be sold-out I think. My brother works there.
Fantastic venue with an amazing state-of-the-art sound and light system, and Steve's Lighting for the July show at Leamington Spa was absolutely top-class. If you really want to soak up the atmos and see what Steve is really all about up there in his spotlight, stand further back near the mixing desks. There's ebven a balcony, with some seating. Maybe move around? Am I right, you're going to The Stables?? If so, that's intimate and you'll be up close and personal in that one. Indigo2 is a largish arena, so being back a bit is definitely the way to go. You must be very excited!! I'll try to find you and say hi, with my wife and two other SH rebelfreaks.
